NOTES:
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
2. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer. It is
a measure of the error in step size.
